Giorgi I Gurieli was a son of Kakhaber II Gurieli by his wife Anna and his successor as the ruler of Guria, a semi-independent polity which emerged in the process of dissolution of the Kingdom of Georgia, finalized in 1491.
As a result, the ruler of Guria became a prince-regnant (mtavari), formally a vassal of the King of Imereti.
Giorgi Gurieli remained more or less loyal to his royal suzerains, Alexander II and Bagrat III,[1] and held the rank of Grand Master of the Household (msakhurt-ukhutsesi) at the court of Imereti.
[2] Mzechabuk's charter, granting the rights over the Zarzma Monastery to the see of Atskuri, mentions territorial acquisition from the Gurieli.
He was succeeded, with the blessing of King Bagrat III, by his son Mamia I.
